Science Buddies: "Ask an Expert"

I am going out for a science class and I was hoping I could get help finding out a few things, I am testing in a lake, pond, or stream for:
1: Dissolved oxygen level
2: Ph level
3: Phosphate level
4: Temperature
I need help finding a few (about 4) resources (even phone numbers) I could use to get information about this if that is possible.










Thank you for your time,

Hi,

Have you done a Google search for these topics? Or Youtube?

Is this part of a science project?
